WET Laboratory Certification

All laboratories performing WET testing for WPDES permit compliance are required to be certified or registered under
ch. NR 149, Wis. Adm. Code. Because high quality data is important when making sound environmental decisions, the
laboratory certification program
establishes minimum requirements for laboratories which when followed, results in traceable and well documented data. In
order for a laboratory to apply for certification or registration for acute and chronic WET testing, the laboratory must
submit a completed application to the laboratory certification program and complete an on-site evaluation.
